Which from the following concentrations of a weak electrolyte solution exhibits maximum molar conductivity?

Which from the following concentrations of a weak electrolyte solution exhibits maximum molar conductivity?
  1. $\quad 0.004 \mathrm{M}$
  2. 0.002 M
  3. $\quad 0.005 \mathrm{M}$
  4. $\quad 0.001 \mathrm{M}$

Solution

The molar conductivity of weak electrolytes increases rapidly on decreasing concentration. $\therefore \quad 0.001 \mathrm{M}$ weak electrolyte solution exhibits maximum molar conductivity.
